How to Release Manganese and Other Metals from Soil Reserves

June 23, 2020

When soil biology has an oxidizing effect, the supply of bioavailable manganese, iron, copper, cobalt, and other minerals is greatly decreased. In this webinar, John describes why excessively oxidized soils lead to tied up manganese and other metals. He also describes how to change cultural management practices to shift soils to a more reduced state and release mineral metals that are unavailable to plants when the soil is oxidized.

Managing Vascular Bacterial Infections

May 15, 2020

In this webinar, AEA founder John Kempf describes how to prevent vascular bacterial diseases with organic practices. Pierce’s disease, bacterial canker, citrus greening, crown gall, and many other diseases share a common mechanism. Each is caused by bacterial populations plugging the plant’s vascular tissue, preventing transport of nutrients and water in the plant. By understanding the root causes of these diseases we can begin correcting nutrition imbalances and cultural practices to increase resistance and reduce severity. View the slides here.

How to Address Micronutrient Deficiencies

April 23, 2020

In this webinar, John Kempf reviews micronutrient and trace mineral function and how to address deficiencies of these minerals. He discusses which can be applied to the soil, which should be addressed with foliar applications, and which can be released from the soil mineral matrix with biology, as well as what form of the trace mineral to apply for maximum effectiveness. He also reviews which lab reports you can rely on to give accurate information about the levels of each of these nutrients. Watch this webinar to learn specifics for each micro and trace mineral:

  • Relative accuracy of soil, tissue, and plant sap reporting for assessment of nutrient levels in the soil and plant.

  • Whether soil or foliar, liquid, or dry applications are most effective.

  • The nutrient form for maximum plant uptake.

  • Management practices that maximize the utilization of soil reserves

Growing Wine Grapes with Regenerative Systems

March 18, 2020

Watch to learn the growing techniques and application practices of a master viticulturist.

Impact of The Rhizophagy Cycle on Nitrogen Efficiency in Broadacre Crops

February 25, 2020

In this webinar, John Kempf discusses a novel approach to nutrition management that has helped farmers improve crop health and profits while increasing resilience to weather stress. Listen to learn how plants absorb and utilize different forms of nitrogen, how some forms of nitrogen increase a plant's water requirements, how to greatly increase nitrogen use efficiency, and reduce application rates. John also describes how plants absorb microbes directly from the soil, how to get the greatest benefit from seed treatments, and how to use other nutrients to get the same growth energy that nitrogen delivers, but with much higher quality. This approach to managing nutrition differently results in improved resistance to pests such as corn earworm, spider mites, aphids, and more.

Regenerative Systems for Growing Hops

February 11, 2020

In this webinar, John Kempf identifies the key critical points of influence (CPIs) during the hop growing season when targeted nutrition delivered through foliar applications and soil-applied biology can result in higher yields and better quality cones to suit a demanding market. John will highlight the key botanical dynamics in play at the time of each critical point, including:

  • Spring and fall biological primer soil applications

  • Transplant root dip and baby hop fertigation

  • Vegetative phase foliar application

  • Reproductive switch foliar application


AEA uses plant sap analysis data to indicate where nutrient deficiencies and excesses exist and form responsive, custom nutrient applications. John also discusses how our nutritional management protocols can help in the management of mites and aphids and decrease nitrate levels in hop cones.

Managing Nutrition at Critical Points of Influence

January 24, 2020

John Kempf discusses how to reach the maximum genetic capability of your crop by recognizing critical points of influence. All crops have cycles during which either vegetative or reproductive energy is dominant in the plant. At the peak moment of each cycle, and again when the cycle switches from vegetative to reproductive, plants enter a critical window of time at which the correct support is paramount for yields and quality. In this video, learn about these critical points of influence, how to observe their occurrence in crops, and how to influence outcomes by applying nutrition and other inputs differently at each critical point. See the slides for this webinar here.

Regenerative Practices for High Yielding Cotton

January 22, 2020

In 2019, a group of cotton growers in the High Plains region of Texas began to use a regenerative agriculture system with a goal to increase the cotton quality and yields on their operation. The results were expectedly incredible, with more than 1,850 lbs. of $.56 cotton in a bad cotton year.


In this webinar, John Kempf, founder of AEA, and Chad Wall, owner of Natural Ecosystem Restoration, describe how to work with the inherent genetics in cotton to balance reproductive energy and eliminate the need for PGPR applications. This practice increases the growing days available to the plant by 20-30 days while reducing plant internodal spacing for ease of harvest. By applying precise inputs needed at critical points of influence, the cotton grown on this system maximized photosynthetic capacity in a short growing window and produced abundant, mature, high-quality lint.

How Healthy Plants Create Healthy Soil

November 1, 2019

In this recorded webinar, John Kempf explains how growing healthy plants can result in the creation of healthy soil. Many growers focus on amending their soil to grow a healthy crop which is much less powerful than growing healthy plants that produce soil root exudates, products of photosynthesis. These exudates, in turn, fuel the soil microbial metabolism and build the soil. This is valuable because, without the contribution of plants, soil only amounts to broken-down rock particles. Listen to this webinar for a clear description of the cycles with which healthy plants can regenerate soil biology in as little as one season. View the slides here.

In this webinar, John provides an in-depth look at these seven micronutrients. For each one, John discusses their functions within the plant, as well as the disease and insect prevention benefits each can provide with the correct management. John also talks about micronutrient mobility within the plant and the different methods of chelation. Watch this webinar to learn:

• Important aspects in the management of each micronutrient 

• Application of xylem-mobile versus phloem-mobile nutrients

• The difference between synthetic and organic acid chelation

Slides can be seen here.

Managing Crop Nutrition During Reproductive Periods

June 26, 2019

At AEA, we recognize that many crops have the genetic potential to produce far greater yields than are routinely harvested. A critical limiting factor that often contributes to decreased yields is insufficient support of the plant’s reproductive functioning.


Two reproductive processes are key to bigger yields — bud initiation and pollination. In addition, plants need enough of the right nutrients to keep from aborting the increased fruit set. We often see plants dropping as much as 75% of their blossoms and immature fruit. We observe this so often that we begin to accept it as a set of normal circumstances, but it can be prevented.


In this webinar, John describes how blossoming, pollination and fruit development in plants can be likened to the human female reproductive processes and which minerals provide the hormonal and nutritional support needed to build a crop. For more information call the AEA customer support team at 800-495-6603 at ext. 344.

The Benefits of Humic Substances in Agriculture

April 24, 2019

Humic substances have a high anion exchange capacity which allows them to hold nutrients such as nitrogen and phosphorus in the soil and prevent them from leaching. There are three different fractions of humic substances generally referred to as humic acid, fulvic acid, and humin. 


In this webinar, John describes the roles of these three fractions, how manufactured humic acids and fulvic acids are produced, and where and how to use them most effectively. John also describes HumaCarb, AEA’s humic acid product, why it is more effective than other humic acids, and how to use it. See the slides here.

How is Regenerative Agriculture Better?

March 21, 2019

To develop regenerative agriculture systems on our operations, we need to begin thinking differently about agronomy, and how we manage plant nutrition. The agronomy needed to develop regenerative agriculture system is based on a group of core concepts which reconsider nutritional priorities and applications. Thinking differently about agronomy will lead to systems which require fewer inputs, and are much more profitable.


In this webinar, John Kempf describes a foundational outline of how a regenerative system works, how it is possible to regenerate soil with limited inputs, how to gain greater results by focusing on the plant photosynthetic engine, and how a regenerative system is more profitable for the grower. 

Sap Analysis and Nutritional Management for Honeycrisp Production

March 15, 2019

Following John’s presentation at Cornell’s Winter Fruit School, many growers have had questions about how to use sap analysis and what nutritional protocols growers are using. In this webinar, John Kempf outlines the nutritional frameworks that have been used at AEA to help develop disease resistance and improve fruit quality. John also describes how to collect sap analysis samples to determine exactly what your trees nutritional requirements are and to measure product performance. When you test you don’t have to guess.

The Plant Health Pyramid

January 30, 2019

At AEA, we have become very well-known for helping farmers produce crops that show resistance to diseases and insects. As we have accomplished this in the field on many types of crops, we’ve noticed a gradual evolution of plant health as plants become healthier and healthier at different stages of nutritional integrity. 


In this webinar, John Kempf outlines these different stages of plant health. Watch to learn about the four distinct stages and:

  • The integrity of plant physiology at each stage

  • The pests which plants develop resistance to at each stage

  • The biological steps behind each stage


This webinar is an in-depth guide to understanding plant health and how you can grow the healthiest crops possible. See the slides here.

December 19, 2018

In recent years, the amount of information available around regenerative agriculture topics has rapidly expanded. This knowledge base involves thinking about the farm holistically as a complex ecosystem.


How can we best sort through and process all this diverse and valuable information? How do we prioritize the opportunities for regenerative planning for our operations? Will we get the best results from remineralizing our soils, using microbial inoculants, or adding biostimulants?


In this webinar, John discusses a framework for organizing a regenerative strategy on your acreage. Watch to learn about the relative impact of various cultural management practices and their hierarchy of importance, the co-dependencies of nutrient and soil amendment applications, microbial products, cover crops, and other factors, and how to develop synergistic stacks which can improve crop performance and soil health the most rapidly with the least amount of input.

Biological Inoculants on Grain Crops

Thursday, April 18, 2018

Many soils are disease enhancing; they weaken the root systems of plants, and cannot deliver enough nutrients fast enough to fill a crop. We are hosting a webinar where John Kempf will discuss the problem of poor soil vigor, the impact on your crop and bottom line, and the tactics farmers can use to jumpstart a poor soil and regenerate it quickly. This webinar will be especially useful for corn and soybean growers and will provide economical solutions for the challenge to maintain profits within the current volatile markets and uncertain weather patterns.

Tools for Plant Diagnostics of Mineral Nutrition

Wednesday, March 21, 2018

In this webinar, John Kempf will teach growers and agronomists how to measure and manage plant nutrition to produce the healthiest plants and highest yields possible.

To effectively manage nutritional integrity, we need to be able to measure it. We understand that by waiting to visually diagnose pests and disease, they will already have caused damage to the crop. 

However, traditional nutrient analysis results do not correlate with disease and insect susceptibility. We should be able to predict pest susceptibility based on lab reports, but we have been unable to do so.

In this webinar, you will learn how nutrients move and interact in plant tissue, and how to predict and prevent nutritional deficiencies. John will also talk about how timely foliar applications of nutrition can reverse disease and insect susceptibility in hours or days.

Why Plant Disease Increases Before Harvest

Wednesday, March 7, 2018

John Kempf describes how physiological changes occur in plants, and how farmers can use targeted nutrition and an understanding of hormonal processes to ensure healthy plants throughout the season and beyond harvest.

Managing Microbial BioStimulants

February 22, 2018

John Kempf, a leader in regenerative agriculture speaks on how to develop synergistic combinations that partner microbial biostimulants with specific inoculants and nutritional support.

Increasing Milk Production Per Acre

February 5, 2018

Because grass-fed cows base their diet on, well, grass… said forages need to have a high nutritional content in order to support the dietary needs of the animal. Many farmers don’t realize they have the ability to raise the fat content of their forages to a point that would make many of the commonly fed supplements unnecessary. 

Advancing Eco Agriculture hosted this webinar to talk about how nutritional inputs increase the metabolism and energy level of plants, so that they have an increased ability to pull minerals and other compounds from the soil, leading to an increase in their value as a feedstock.  

Nutrition In Stone Fruit Production

February 7, 2018

Fruit size and quality are primary concerns for fruit growers. At a time with especially volatile natural weather events, orchards need to be even better equipped to resist shock, extreme temperatures, and disease pests, and continue to produce high-quality crops. 


In this webinar, John talks about how the AEA program increases fruit size and quality in stone fruit production. John presents steps to implementing an effective crop nutrition program, the tools AEA consultants use to solve difficult disease problems, and important information on key nutrient considerations that affect fruit size and quality.

Preventing Yield Loss at Planting

February 25, 2018

In this webinar Nathan Harman presented the framework of critical points of influence in relation to early growth stages. Critical points of influence is the framework that the agronomy team at Advancing Eco Agriculture uses to determine when fertility inputs will have the most impact and when they should be applied.

Answers to Spider Mite Pest Pressure in Organic Grain

October 9, 2017

Spider mites are attracted to corn plants with a specific nutrient profile which meets their nutritional requirements as a food source. When the nutrient ratios are shifted, corn plants become much less desirable to spider mites, and pest pressure can be substantially reduced. In this video, John and David describe how to manage plant nutrition to produce crops which are mite and insect resistant.


Brad Koehn also describes his experiences in working with Advancing Eco Agriculture’s plant nutrition products and management strategies. He has observed foliar applications of plant nutrition products prevent and reverse mite infestations on organic and conventional corn crops, achieving perfect control without any miticide applications.

August 4, 2017

Mike Omeg of Omeg Orchards and David Miller of Advancing Eco Agriculture talk about Mike's experiences using foliar nutrient applications after harvest to increase fruit size on Omeg Orchards in The Dalles, Oregon.

Building Soil Organic Matter While Your Crop Is Growing

November 24, 2015

Today it is accepted as normal for crops to deplete soil organic matter while they are being grown. The common solution to this problem has been to grow and incorporate a cover crop after the crop has been harvested to rebuild these nutrient reserves. 


John will explain how to build organic matter and biology simultaneously while growing your crop by accelerating plant photosynthesis. 

Capturing Residue to Build Soil Organic Matter

November 3, 2015

Building stable soil organic matter has nothing to do with how much crop biomass is captured in the soil profile. Instead, it has everything to do with how the lipids and complex carbons are digested by fungi.


John Kempf, agronomist and founder of Advancing Eco Agriculture, talks about the methods we use to build soil organic matter very rapidly by triggering specific digestion processes to capture crop residue after harvest and root exudates during the growing season.
